Pulse frequency variations and timing noise of MXB 0656-072 during the 2007-2008 type I outbursts and implications for its magnetic field
M. Mirac Serim, Danjela Serim, Çağatay Kerem Dönmez +4
We aim to explore the properties of the Be/X-ray binary system MXB 0656-072 from a timing analysis perspective through an investigation of the RXTE/PCA and Fermi/GBM data during it…
Timing analysis of Swift J0243.6+6124 with NICER and Fermi/GBM during the decay phase of the 2017-2018 outburst
M. M. Serim, Ç. K. Dönmez, D. Serim +3
We present a timing and noise analysis of the Be/X-ray binary system Swift J0243.6+6124 during its 2017-2018 super-Eddington outburst using NICER/XTI observations. We apply a synth…
Pulse Frequency Fluctuations of Persistent Accretion Powered Pulsars
D. Serim, M. M. Serim, A. Baykal
In this study, we examine the long term torque noise fluctuations of persistent Xray binaries Her X-1, Vela X-1, GX 301-2, CEN X-3, 4U 1538-53, OAO 1657-415 and 4U 1626-67 using th…
Timing and spectral analysis of 2S 1417624 during its 2018 outburst
M. M. Serim, O. C. Ozudogru, C. K. Donmez +4
We investigate timing and spectral characteristics of the transient X-ray pulsar 2S 1417624 during its 2018 outburst with \emph{NICER} follow up observations. We describe the sp…
Comprehensive Analysis of the Transient X-ray Pulsar MAXI J1409-619
Ç. K. Dönmez, M. M. Serim, S. Ç. İnam +3
We probe the properties of the transient X-ray pulsar MAXI J1409619 through \textit{RXTE} and \textit{Swift} follow up observations of the outburst in 2010. We are able to phase…
Episodic Torque-Luminosity Correlations and Anticorrelations of GX 1+4
M. M. Serim, S. Sahiner, D. Cerri-Serim +2
We analyse archival CGRO-BATSE X-ray flux and spin frequency measurements of GX 1+4 over a time span of 3000 days. We systematically search for time dependent variations of torque…
